Also known as "The Disguise Master and the Marriage"
Duan Yisheng, the quirky little prince of Dali Kingdom, originally wanted to save a young girl who was being used as a political tool and wanted to marry the Central Plains. However, by some strange combination of circumstances, he mistakenly embarked on the road to the Central Plains marriage. Not wanting to make a mistake, the marriage partner, the fourth prince of the Central Plains, Jin Wang Wei Beiqin, turned out to be a good match for Long Yang.
Then there is the story of how Duan Yisheng was forcibly converted and accompanied his husband to conquer the northwest and repel the Mongols.
Wei Beiqin: "I didn't expect you, Dali Kingdom, to be so sensible. I am as good as Long Yang, so you gave me a prince. Don't worry, I will love you well."
Duan Yisheng: "Beast, let me go, I'm not here for a kiss!"
